stampings, screw machine products, valve casings, and' like articles which require treatment in order to relieve them of oxid and other foreign substances collected during the course of manufacture.

The object of the invention is to provide a continuouslyl operating machine adapted to feed materials therethrough whereby to permit the materials to be subjected to a bath of a suitable solution, and to a washing bath so as to cleanse them of all foreign substances engendered during the course of manufacture, the construction and arrangement of the machine being such that the articles passing through the machine are first subjected to a bath of a cleaning solution, and then subjected to another bath and washed of the cleansing influence before being delivered through the discharge end of the machine. A further object of the invention is to provide an arrangement whereby to subject the articles passing'through the -machine to a tumbling or agitating movement, so as to insure an immersion and washing of the materials before being discharged at the delivery end of the machine.

The invention comprises a cylinder adapted to be continuously rotated and having an internal helical or spirally arranged web or blade extending throughout the length thereof providing a helical channel for feeding materials through the cylinder; in the arrangement of scoops carried by the cylinder and associated with tanks designed for containing acid or other cleansing solutions, said cylinder being provided with perforations whereby to permit the liquids collected by the scoops to flow into the Acylinder upon the articles as they are fed therethrough. The invention further comprises means for washing the articles after passing through the cleansing iniuence, and in certain pecullar and novel features of-construction and arrangement whereby waste of the solution is avoided, and still vfurther in the novel and peculiar construction of the machine whereby the articles passing through the machine are immersed and rinsed before being delivered. l

In the drawings, illustrating the invention, in-the several figures of which like parts are similarly designated, Figure 1 is a side elevation of the machine. Fig. 2 is a longitudinal section of the machine. Fig. 3 1s a transverse section drawn on the line .A-A of Fig. 2, showing the scoop or dipper immersed in the cleaning influence holding tank, and Figs. 4:, 5, and '6 illustrate the several positions of the scoop or dipper durmg the revolution of the cylinder.

1 designates a cylinder of substantially uniform diameter throughout its length supported by rollers 2 operating upon circumerentially arranged bands or tracks 3 carried by the cylinder. The said rollers 2 are journaled in brackets or frames 4, and are so disposed to holdv the cylinder lin a substantially horizontal position. The cylinder 1 is designed to be rotated upon the rollers 2, and, for the purpose 'of illustration, I show the cylinder 1 provided with a band or rim of sprocket teeth 5 over which operates a drive sprocket chain 6 extending from a suitable source of power (not shown).'. It will be appreciated that while I have shown and spec1 ed a sprocket and chain 'mechanism for revolving the cylinder, thatv other mechanism may be employed for revolving the cylinder, and that the mechanism may be located in other positions than that shown in the drawings of the present application. While I have shown the cylinder 1 mounted upon rollers 2 supported in frames located at the inner and outer ends of the cylinder, it will -be apparent that other supporting rollers may be employed according to the length of the cylinder. s

Carried by suitable brackets (not shown), positioned adjacent to the inner end of the cylinder 1, is a hopper 7 having its discharge 7 opening into the inner end of the cylinder l. The cylinder is formed with an internal spirally arranged web or blade 8 extending throughout thc length thereof providing a s' iral or helical groove or channel 8' adapted tor feeding the materials through the cylinder.

Located adjacent to and below the inner or forward end of the cylinder 1, is a tank 12, adapted for holding a solution of sulfuric acid or other cleansing solution. The cylinder 1 is provided with a scoop or dipper 9 (pen at one end and closed at its opposite r-n and adapted to operate through said tank 12 during the revolution of the cylinder. v The cylinder is provided between the end walls of the scoop or dipper with a plurality of perforations 11 designed to permitthe feeding of the liquid into the cylinder and the escape of the liquid from the cylinder back into the tank 12 during the revolution of the cylinder, thereby flooding the channels 8 and completely iinmersing the articles as they are fed through the machine. In order to avoid any waste 0f the cleansing influence, the cylinder 1 is provided with a plurality of circumferentially arranged perforations 13 located immediately forward of the scoop or clipper 9, which servev to drain the liquids fed into the channels 8 forward .of the scoop or dipper 9. Adjacent to the outer end of the cylinder 1 there is located a tank 14 adapted for containing a solution of soap and water or other suitable cleansing or washing solution, and operating in con junction with this tank 14 is a scoop or diplper l5 carried by the cylinder 1, and whic like the scoop or dipper' 9, is open at one end and closed at its opposite end, and is adapted to collect the solution contained in the tank 14 and spray and immerse the material as it is fed through the cylinder. The Y cylinder between the end walls of the scoop or dipper 15 is provided with perforations 16, whereby to permit the inflow and discharge of the liquid upon the material as it passes through the cylinder. lmmediately forward of the scoop or dipper 15 the cylinder is provided with a plurality of circumferentially arranged perforationsor slots 17 whereby'to collect and drain back into the tank 14 the liquid that has been previously scooped up by the scoop or dipper 15. Arranged centrally within the outer end of the cylinder 1 is a pipe 18 having a plurality of perforations 19, said. pipe being designed for supplying cleansing water to the materials to wash them of the first cleansing influence and subject them an immersion of pure water, which is drained ott1 through perforations 2O into a drain hopper 2l located below the cylinder and having a suitable drain pipe connected there` to for carrying off the water as it escapes through the perforations 20. lnimcdiately adjacent to the outer end of the cylinderv the latter is provided with peroratioiis 2G),

mtime and the pipe 18 is provided with plurality1 of perforations 19', through which cleansing water is sprayed upon. the materials before being delivered from the cylinder. A drain hopper 21 is arranged below the perforations 20 for carrying off the cleansing water as it escapes through the perforations 20.

The operation of the machine is as follows Taking, as an example, small brass pieces coming from an annealing furnace, and which are consequently coated with oXid, they are dumped or poured into the hopper 7 from' which they flow into the groove or channel 8 at the forward end of the machine, and through the rotation of the cylinder, it will be appreciated that the inaterials `are fed therethrough in a manner similar to thatof all screw conveyers. Now as the'materials pass through the channels 8 embodied within the length of the scoop or dipper 9, they will be sprayed and immersed in a suitable cleansing solution collected from the tank 12, and as the solution is fed into the channels 8, immediately forward of the scoop or dipper 9, the solution will run back into the tank, through the perforations 13, and hence used over and over again. As the articles continue through the machine they are subjected to an inime'rsion of fresh water supplied by the pipe 18, rinsed, and this rinsing water is drained through the perforations 2O formed "in the cylinder 1. Then as the articles are passed through the cylinder they are subjected to a bath 0f the solution contained within the tank 14 in a similar manner as that described with respect to the scoop or dipper 9, after which the articles are subjected to a further washing, rinsing, and draining before being delivered out through the free end of` the cylinder.

lt will thus be seen that l provide a very simple and highly eflicient apparatus for the purpose described, and it will be understood that while l have shown only two solution containing tanks and two scoops or clippers associated therewith, that a greater number may be employed should occasion require. I ,therefore do not limit myself to any specilc number of scoops or dippers andtanks, or solutions or washes, as it will be obvious to anyoneiskilled in the art to which the invention relates that a greater or less number may be employed without departing from the spirit of the invention.

It will be particularly' noted that the inlet and escape ports or perforations of the cylinder are arranged at intervals throughout the length thereof so that as the materials are fed through the helical channel they are subjected to an immersion, and that the solutions or watertin which the materials are immersed are drained and 'led back into the 'ae-ences ternally ar anged helically disposed member for conveying work therethrough, means eX- teriorly arranged upon said drum for auto--v matically supplying fluid to the. work passing through said drinn as the drum is rotated, said drinn having a plurality of discharge openings to permit of the escape of the fluid at intervals during the passing of the work through the drum.
